Background technology
The twin axle pulverizer of this structure type is used for comminuted solids, for example organic substance (as branch, withe, plant) or other material (as waste plastics).At this, solid to be pulverized can be supplied to the twin axle pulverizer with the form of drying or with the form of liquid stream by entrance.
For efficient pulverizing, the twin axle pulverizer has two axles, on these two axles, a plurality of blades is set respectively.These blades are interlocking mutually alternately, this can realize and reach by following manner, that is: form axial spacing between two of an axle adjacent blades, this axial spacing is greater than the thickness of the blade of another axle, and the mutual distance between axles of two axles is less than the diameter of a blade.
Two axles of twin axle pulverizer are typically driven by subtend ground and for example mutually are coupled via corresponding transmission mechanism for this purpose.Especially during with different rotational speed, just obtain good crushing effect when two axles.By this way, the blade by subtend in the gap between two axles produces high shearing force and pull-off force, and this causes the efficient pulverizing of solid.Different rotating speeds causes in addition, and when each the rotation, the different cutter section section of each adjacent blade is rabbeted mutually, and described blade is automatically cleaned by the comminuted material that adheres to thus.
The shortcoming of the twin axle pulverizer of this structure type is, due to two axles and the mutual forms of motion of blade that is arranged on these two axles, when hard solid body arrives in crushing chamber and is stuck between two blades or when being stuck between blade and opposed axle, can damages indivedual blades.Therefore, blade can seriously be damaged in the zone of its cutting edge, and the continuation of twin axle pulverizer operation no longer may or only be carried out with less grindability thus.
Be known that for this purpose, the twin axle pulverizer is equipped with fast replacement system, in this fast replacement system, each blade can be pulled down from axle individually, in order to change impaired like this blade.Therefore realize: can expend with few maintenance and few replacing part cost recovers the operability of twin axle pulverizer.
Another shortcoming of known twin axle pulverizer is, by be between two intermeshing blades or be in a blade and and the opposed axle of this blade between solid body, can cause the significant torque peak on these two blades or one of them blade.This torque peak can have following consequence,, can remove blade supporting on axle that is antitorquely.Antitorque fixing this damage by blade on axle can make the continuation operation of twin axle pulverizer become and can not or only continue operation with limited efficient, and particularly follow the further danger that damages of other member of pulverizer to continue operation.
Summary of the invention
The purpose that the present invention is based on is, a kind of twin axle pulverizer is provided, and it is avoided or alleviates at least the problems referred to above.
the following realization of purpose according to the present invention, namely, by with each the first blade single type be molded on the first hub body, each first blade constitutes the first blade piece, described the first hub body has axial hole, this axial hole can be around the part setting of the first axle, and described the first hub body preferably is fixed on the first axle by means of the sealed axle of shape-hub connects antitorquely, and by with each the second blade single type be molded on the second hub body, each second blade constitutes the second blade piece, described the second hub body has axial hole, this axial hole can be around the part setting of the second axle, and described the second hub body preferably connects and is fixed on the second axle antitorquely by means of the sealed propeller boss of shape.
